Yosef Karo

“ Paragraph 1 - One is permitted to send his friend game, an animal or a chicken, even living ones, or wines, oils, flours, and legumes, but not produce because that needs to be ground, which is a forbidden labor on a holiday. ”

“ Paragraph 2 - When it is permitted to send something on a holiday, one should not send it in a line, meaning three or more men in a line carrying one type of thing. If each one carries something different, it is permitted.
סעיף ב - כל דבר שמתר לשלח יום טוב לא ישלחנו בשורה, דהינו ג' בני אדם או יותר זה אחר זה נושאים כלם מין אחד, אבל אם כל אחד נושא מין אחר, מתר. ”
